Why are there differences in men vs. women weight loss? As a weight loss expert with over two decades of experience, I will tell you why.

I have seen this firsthand in my private practice. Women do it all and cut out all of the things they love: the chocolate, bread, and wine, and they lose one pound after a week. Not too bad. Men? All they give up are the sodas and guess what happens? They lose 4 pound in a week! You may be wondering how this is possible. What is the cause of this disparity in men vs. women weight loss?

Setting Realistic Weight Loss Expectations

In my practice, I often hear female clients complain about how easy it is for their husband or boyfriend to lose weight. They report that even when staying on track, they can’t shed the pounds. Another set of clients complain that they are not losing weight at the same rate as people on TV shows like The Biggest Loser and Shedding for the Wedding.

Some of them are expecting to lose 10-plus pounds per week like the TV shows portray, but that just isn’t realistic for most people. Their frustration is evident, and it breaks my heart; that’s why I am writing this blog — to set the record straight. I have news for everyone: All weight loss is not created equal!

Men vs. Women Weight Loss

Losing weight is a totally different experience for women than it is for men. Assuming that all emotions are in check, physiologically speaking for men, losing weight is pretty straightforward. Men can stop drinking sodas or cut down on fast food and just drop 20 pounds. But this is not the case for women. They can stop drinking soda, stop eating bread, and even stop enjoying chocolate, then hardly lose one pound. Such an incredible, and seemingly unfair, difference! Why?

This obvious inequity is mostly due to differences in body composition, but we can also blame hormones, as they pretty much control every motivation we experience. To add to the disparity in weight loss between genders, there is also variation depending on how much weight needs to be lost.

Let’s begin with the differences in weight loss between men and women.

Why Do Men Lose Weight Easier Than Women?

Men naturally have more muscle mass than women, and muscle is metabolically active tissue, so it expends energy (burns calories). They also have more testosterone, which further enhances the lean muscle tissue that burns more calories than body fat, even during rest.

So, the more muscular a person is, the higher their metabolic needs are. Generally speaking, this is why men are able to melt fat more quickly than women when losing weight.

And, when men and women cut the same number of calories, men usually do lose more weight. Men in general just tend to lose body fat, while women find this harder to do. Again, men can thank testosterone for that.

Healthy Body Fat and Fat Loss for Women

On average, women have between 6-11% more body fat than men, and this is because, due to evolution, women need to keep more body fat on them for a healthy pregnancy.

So, from puberty to menopause, women maintain more average body fat than men — even when they take in fewer calories. It’s just biology.

Female’s fat stores are typically more spread out than men, which is partly why they lose weight at a slower pace than guys.

Female Hormones and Weight Loss

For women, changes in hormone levels during the menstrual cycle ‘rev up’ the metabolism and cause overeating due to food cravings as well as increased appetite.

Did you know that in the pre-menstrual phase, a woman’s metabolic rate can be10-15 percent higher than normal? Doesn’t that explain a lot? Additionally, women often add exercise programs to jumpstart weight loss, not knowing that exercise increases another hormone, Ghrelin, which stimulates appetite and initiates hunger(1,2,3).

It may be tempting to skip a meal thinking that you can ‘save’ calories this way, but working with the body’s signals rather than fighting them can actually prevent overeating. When hunger strikes, give your body what it needs by eating something small and sensible.

And don’t forget – menopause throws in a whole other curveball. I’ve seen enough women struggle during this phase that I have a whole separate post on menopause and weight loss.

Achieving Realistic Weight Loss

Weight loss also differs according to how many pounds one aims to lose.

Weight Loss Goal: Lose 5-10 Pounds

If you want to lose 5-10 pounds (I call this fine tuning, not weight loss), your body will have to work the hardest to achieve your goal. Expect 0.5 – 1 pound loss per week, and don’t bother putting in overtime at the gym since extra exercise will only shut your metabolism down rather than burn off fat because you are likely already restricting calories.

Folks in this group do not have excess fat, so the body is holding on to it like you would hold on to a two-billion dollar winning lottery ticket. This group is unique, and for them the key to weight loss is 90 percent diet and only 10 percent exercise. For you, eating too little and exercising like a maniac is not going to help you fine tune your weight.

Weight Loss Goal: 20-60 Pounds

Those who need to lose 20 – 60 pounds can expect about 1 – 2 pounds per week to come off. A combination of cardio and weight training can help maintain critical muscle mass while shedding mostly fat. For this group, the key to successful weight loss is 80 percent diet and 20 percent exercise.

Weight Loss Goal: 80+ Pounds

For people who need to lose over 80 pounds, weight loss is fastest, usually at 2 – 3 pounds per week. High impact exercise is not recommended for those in this category as it puts too much strain on the body, especially at the joints. Low impact activities are best, with walking as the number one way for people in this group to get moving safely (4). Again, it is all about 80 percent diet and 20 percent exercise for healthy weight loss.

Do Guys Lose Weight Faster?

Finally, men tend to lose weight where they need it most. Usually, this is in their belly. So, it’s often more immediately noticeable when overweight men start trimming down than when women start trimming down. This is why I always say when it comes to weight management for men, it’s about waist management.

As mentioned above, ladies’ fat stores are typically more spread out, which is partly why they lose weight at a slower pace than guys.

Takeaway From Men vs. Women Weight Loss

Remember, losing weight is a highly individual experience even with these insights for men vs women weight loss. No matter how much weight you have to lose or what your gender is, patience is key. You cannot control how your body will lose weight or the number that the scale shows you; you can only control what goes into your mouth and your relationship with food!

Change your behaviors and don’t deny hunger. Most importantly, take the time to prepare and plan your meals, and exercise for health (rather than as an excuse to eat). At the end of the day, dropping pounds is hard work for both women and men. And, really, it all boils down to this: anyone can lose weight — it doesn’t matter what your gender is. You just have to be committed to doing it.
